Original Abstract:
The objective of this study is to determine the economic benefit/cost
of spring load restrictions, and based on the findings to determine the
optimal restrictions (increases) or heavy load taxes to minimize the combined
cost of infrastructure and cost to the industry and commuters. In order
to accomplish this objective a number of intermediate objectives would
have to be accomplished first: Review and synthesize the freeze-thaw effect
on material properties and structural capacity to determine how changes
in material properties translate into increased/reduced life of pavement;
Assign pavement-associated costs/benefits to levels of increased/reduced
damage; Determine the demand patterns of large trucks throughout the year;
Estimate the value of freight movement on the road network; Estimate the
costs of substitute vehicle, routes, modes, schedules; Assign industry
associated costs/benefits to various levels of increased/reduced damage;
Develop optimal the combination of taxes and restrictions and network
improvements.
